Random white eggs

[mamalu]

I have found 3 very large white eggs with my normal brown eggs. I have 4 2 year old isa browns. Thoughts?

I don't know how chicken genetics work, and while I understand that extra large eggs may be lighter in color, I've never had a brown-egg-laying breed present me with a white, (not light-colored) egg before

In OP's picture, the big eggs look light but not completely white to me.
I have gotten almost-white eggs on occasion from chickens that normally lay brown eggs.
I think sometimes it's a glitch with the part of the chicken that is supposed to add the brown coating, but with OP finding three in a row there is clearly some kind of a pattern here.


I am really curious to know if the big eggs have single yolks or double yolks.

If they have two yolks, I am pretty sure they are being laid by one of OP's hens.

If they have one yolk per egg, I am pretty sure they are being laid by some different, bigger bird (who must get into the coop to do it, unless a person is putting the eggs in for some reason.)

No ducks

There is no doubt you have a visitor.
Your birds did not lay them.

They sure look like duck or even goose eggs. Could someone be playing a joke on you ?

One way to know...stick 'em in an incubator.

We do have Canadian geese in the field behind our house

There is your answer.

@mamalu, this thread is like a suspenseful book without the last chapter. Five pages of "what could be causing this??" has us riveted. Crack the darn eggs already and let us know, please!

Those are some big eggs. Where exactly did you find them?

In the coop. None of my chicken friends can help.

Have you gotten them every day? I'd try to set up a game cam or something in the coop and see if you can find what's laying them. They look like large domestic duck eggs or goose eggs to me.

This^^^
Were all 3 eggs found on the same day?
